Benefits of technology

This patent describes a system for preventing blood clots in intravenous catheters. The system includes transmitters that transmit energy waves at a specific frequency to vibrate the catheter and prevent blood from clotting. The transmitters may continuously or regularly transmit energy waves along the length of the catheter for a period of time, or they may transmit in pulses. The system may use piezoelectric elements or microwaves to transmit the energy waves. The transmitters may be controlled based on an electrical signal or a baseline signal. The catheter's distal tip may have facets or curved portions to improve energy wave reflection. The system can detect blood clots by monitoring the first frequency or by using sensing elements or transducers. Overall, the invention prevents blood clots and promotes safe blood flow through catheters.

Problems solved by technology

In some instances, an intravenous (IV) catheter, including a peripheral IV catheter, may become unusable or compromised prior to completion of infusion or blood withdrawal using the catheter.
One reason the catheter may become unusable may be due to occlusion of the catheter over time.
Further, catheter occlusions can lead to catheter infection, pulmonary embolism, post-thrombotic syndrome, and other negative health outcomes.

Abstract

A system to detect occlusion of an intravenous catheter may include a housing, which may include a distal end configured to couple to a proximal end of a catheter adapter and an inner lumen forming a fluid pathway. The system may also include one or more transmitters, which may be disposed within the housing. The transmitters may be configured to transmit first energy waves along a length of an intravenous catheter at a first frequency, and a portion of the first energy waves that are reflected back from the catheter may be detected by the system. Based on the portion of the first energy waves that are reflected back from the catheter, the transmitters may transmit second energy waves along the length of the catheter at a second frequency, which may be greater than the first frequency and configured to reduce formation of blood clots within the catheter.

Description

BACKGROUND OF THE INVENTION[0001]In some instances, an intravenous (IV) catheter, including a peripheral IV catheter, may become unusable or compromised prior to completion of infusion or blood withdrawal using the catheter. One reason the catheter may become unusable may be due to occlusion of the catheter over time. Occlusion may result from non-use of the catheter and / or diffusion of blood from the vein slowly into a distal tip of the catheter. In response to the catheter becoming occluded, the catheter may need to be removed and replaced with a new catheter. Catheter occlusions may be thrombotic, resulting from formation of a blood clot or thrombus within or surrounding the distal tip of the catheter. Catheter occlusions may also be non-thrombotic, resulting from precipitates, mechanical obstructions, and other factors. Further, catheter occlusions can lead to catheter infection, pulmonary embolism, post-thrombotic syndrome, and other negative health outcomes.[0002]Accordingly, ...
